Sometimes, a murder mystery novel wastes no time at all in getting to the action at the heart of its plot. Early on, we know who was murdered and how; the only question left is who did it—and, by extension, why. In that case, you’re most likely reading a whodunit. A slang term for the phrase “who [has] done it” that caught on in the 1930s, whodunits soon blossomed into their own subgenre. In these absorbing reads, the plot centers on deducing who the murderer is, and the reader is encouraged to solve the case right alongside the presiding sleuth. It’s the perfect option for mystery fans who love a good brain teaser—and for armchair sleuths itching to crack a case!

10 of the Best Whodunit Books
The Dutch Shoe Mystery
What better way to top this list than with a whodunit from Ellery Queen? After all, Queen is “the most important American in mystery fiction,” according to Edgar Award-winning editor Otto Penzler. Ellery Queen is actually the pseudonym for cousins Frederic Dannay and Manfred Bennington Lee, who co-wrote dozens of crime fiction books together; it’s also the name of their most popular fictional character and the star of The Dutch Shoe Mystery.
As the son of a policeman, Ellery Queen knows a thing or two about crime scenes. And this one is the most baffling he’s encountered yet: an heiress is scheduled for surgery, but before she’s wheeled into the operating room, doctors find her strangled to death on her gurney. Who would do such a thing, and why?
There’s a lot riding on your shoulders when you’re given the nickname “the American Agatha Christie”—but Mary Roberts Rinehart carries the mantle with ease. Published in 1933, this top-notch mystery takes place in a secluded gated community known as Crescent Place. Over the years, the residents of Crescent Place have grown increasingly wary of outside intervention, to the point that their streets resemble a time capsule from the 1890s. But when a bedridden old woman in the community is killed with an axe, avoidance is no longer an option. It’s time for her neighbors to break their silence and acknowledge the world outside their small, strange enclave.

Henrietta Who? was first published in 1968, and belongs to English author Catherine Aird’s long-running Calleshire Chronicles.

In The Case of the Lazy Lover, defense lawyer Perry Mason receives two rather large checks in the mail from a woman he doesn’t even know.
